2021 — No regular exam held this year: Tamil Nadu cancelled the March 2021 Class 9/10/11 Public Examinations outright (COVID-19 2nd wave) — students were promoted using their quarterly/half-yearly marks, so no genuine full-cohort exam was ever sat. The single "September 2021" paper on DGE’s own archive that year is a private-candidate/improvement sitting, not the regular annual exam, so it is not published here (mirrors this platform’s standing "main sitting only" convention, applied identically to TN-DGE’s Class-12 2021 papers).

2018 — Paper not yet available: This is the TN-DGE Class-11 (+1) Public Examination’s debut year (2017–18). Sibling subjects from the same sitting ARE archived, but no verified original question paper for this specific subject has been found from any source we check (official DGE archive, trbtnpsc.com, padasalai.net, nammakalvi.com, kalviexpress.in). We publish only a paper we can verify against a real printed original — this one will appear here once it is.
